A sec-ond truck 17, having` the rontswiw eltd wheel V18 and the rear swivell'cd wheel 19, is hitched o-rattaehedto an extensionV from the cross beam 13 of ther truck '12 asjwith a cable 19A and clevis 2Ov operatingonfthe" U-iron 21 swivelled on' theffront end' of the truck.

The plates 27 are secured to a bar 31 having the turned down end 32 engaging the front or vertical fange of the beam 1324; the bar being free to slide sideways on the beam 13A below the guide bar 33 while the sain guide bar 33 retains the bar 31 in a substantially horizontal position, all as best shown in Figure 5.

From the plow end of the conveyer frame extends a nrel-shaped bracket hinged with a bolt or pin 35 to a iJ-shaped member 36 which in turn is hinged as at and with a bolt or pin 37 to a bracket 38 secured to the plow; the bracket 38 having a horizontally arranged iiange or surface 39 upon which the member 36 rests or bears, all as best shown in Figures 2 and 3.v swing upwardly about the bolt 35 and to swing sidevfrvs or horizontally about the bolt 37. rlhe of r ends of the conveyor' frame members 24, that is the e1 "l" farthest from the plow, may be secured to brackets 43 turning on pivot pins 44 secured in brackets 45; the brackets 45 being secured to a top centre plate 40 turning around a kin` pin and bearing upon a lower centre plaie 41 secured to the top cover plate 424 of the truck beam 46, all as best shown in Figures 4, 6 and 8. Thus the conveyer can swing vertically around the axis of the pivot 44 and swing sideways or hori- Zontally around the king ain 42.

The belt 22 is trained over the rollers 48, 49, and 51 of which 51 is the drive roller; the rollers 48 and 49 being journalled in the memi bers 52 of the conveyer frame, and the rollers 50 and 51 journalled in the members 53 of said frame hinged to the members 52 as at 54. A roller journalled in brackets 56 secured to the members 24 is positioned below the roller 49 to tension the belt 22 when the inembers 53 are swung down below the members 52 as shown in Figure 2.

rlhe members 53 are swung vertically by turning the shaft 55A with a removable crank (not shown) to turn the ratchet Wheels 56A which engage with the quadrants 57 fastened to the members 52 and 24; dogs 58, co-operating with the wheels 56A, releasably lock the wheels in various determined positions along the quadrants.

rEhe truck 17 is reI ained in a vertical position by a spacing member 59 so hinged atboth ends to said truck and plow as to be free to swing upwardly and sideways relative to either; the member 59 being hinged with a pin or bolt 60 to a member 61 which in turn is hinged with a bolt or pin 62 to a bracket 63 secured to the plow and truck respectively, all

best shown in Figures 1 and 7.

lf preferred, two rear wheels (not shown) may be used instead of one wheel 19, in which case the swivelled bracket 65 shown in Figure 1 would be made ubstantially as shown in Figure 10 and indicated as 65A, and the spac- Thus the conveyer frame is free to V ing rod 59 and other depending parts dispensed with.

The driving roller 51 may be driven from the rear swivelled wheel 19. Rigid and centred on the wheel 19 is a crown gear 67 mesh-y ing with a co-acting bevel gear 68 rigid on the shaft 69 journalled in the bracket 65. Rigid on the shaft 69 is another bevel gear 70 meshing with a co-acting bevel gear 71 rigid on the shaft 72. Rigid on the lower end of the shaft 72 is a bevel gear 73 meshing vith a co-acting bevel gear 74 rigid on the shaft 75 journalledin bearings 94. Rigid on the shaft 75 is a bevel gear 7 6 meshing with a co-acting bevel gear 77 rigid on the shaft 78. Rigid on the shaft 78 is a bevel gear 79 meshing with a co-acting bevel gear 80 rigid on the shaft 81 lying in the axis of one of the hollow pivot pins 44. Rigid on the shaft 81 is a bevel gear 82 meshing with a co-acting bevel gear 83 rigid on the shaft 84 which lies in a vertical plane parallel with a vertical plane passed through either of the members 53. Turning with but free to slide on the shaft 84 is a bevel gear 85 having the extension hub and meshing with a co-acting bevel gear 86 fast on the shaft 87 of the drive roller 51. The shaft 84 is journalled in the bearings 91 and 89 which are free to turn on the shafts 81 and 87 respectively; the shaft 84 being constrained against axial movement as with suitable collars 92 and the shaft 81 being similarly constrained as with suitable collars 98. The king pin 42 is made hollow to allow the shaft 78 to lie and rotate in its axis so that the shaft may be free to rotate while the upper centre plate 40 is also free to turn around the king pin and upon the lower centre plate 41. The king pin may be formed with a head 42A bearing on the bottom cover plate 46Bon which head is secured a bearing in which the lower end of the shaft 78 is journalled, the upper end of the shaft 78 is journalled in the bearing 78A the upper end of the king pin being threaded to receive the nut 101 which holds the king pin in position. To similarly allow the shaft 81 to freely rotate in one of the pivot pins 44 which may be formed with a head 103 and threaded to receive a nut 104, a bearing 105 is secured on the nut 104 and journals one end of the shaft while the other end is journalled in the bracket 97. To similarly allow the shaft V72 to freely rotate while the swivel bracket 65 is also free to rotate around the king pin 106, this king pin is made hollow and formed at the lower end with a head 107 and threaded at the upper end to receive a nut or bearing 108, and a bearing 109 secured to the head 107. For obvious reasons a brace 93 and suitable ball bearings 110 are preferably provided as shown in Figures 4 and 9.

Operation: When the device is to be used as a brush breaker, the auxiliary truck 17 is detached by removing the pivot bolt 37 and clevis 21. When used as a road builder and ditcher, the device is left as shown in thev drawings or more 'particularly in Figure 1. By drawing the device forwardly the rota- 'tion of the rear wheel 19 ycauses the endless belt 22 to move. The earth raised'by the plow and elevated onto the belt is carried and dumped on to the ground. The dumping position or elevation is altered by raising or lowering the frame or members 53 by turning the shaft 55A and earth discharged near;

er to or rather from the plow by unwinding or winding the cable 19A on the drum 25.

The front truck is elevated or lowered unii formly by lowering or raising both wheels 15 and 16 equally; either end of the truck is elevated or lowered by lowering or raising the wheel near that end, this being done by working the lever 142 on the quadrant 142A as already described.

Vhat I claim is:

In combined road builders, ditchers and breakers, a front truck having its frame eX- tending transversely beyond the running gear, a plow having its beam extending for wardly to the truck frame and secured thereto and forming a trailer, a tandem truck adjustably secured to and trailing behind the said transverse extension and supported from said plow beam and a transverse conveyer hingedlyA securedto the plow beam and pivotally supported 'by said tandem truck and continuously discharging the earth'removed by said plow in its forward movement. 1 Signed at Ottawa, this 15th day of May,
